Abstract: his paper describes a new gridded, daily 29-yr precipitation estimation dataset centered over Africa at 0.1° spatial resolution. Called the African Rainfall Climatology, version 2 (ARC2), it is a revision of the first ...

Abstract: rought is one of the leading causes of death in Africa because of its impact on access to sanitary water and food. This challenge has mobilized the international community to develop famine early warning systems (FEWS) to ...

Abstract: his paper reports on the development of a new statistical tool that generates probabilistic outlooks of seasonal precipitation anomaly categories over Africa. Called the seasonal performance probability (SPP), it quantitatively ...

Abstract: The ensemble rainfall forecasts over the Sahel for July?September (JAS) from the NCEP Coupled Forecast System (CFS) were evaluated for the period 1981?2002. The comparison with the gauge-based precipitation analysis indicates ...

Abstract: The association between rainfall over the Sahel and Sudan region and tropical storm activity in the Atlantic is examined using the NCEP?NCAR reanalysis and sea surface temperature anomalies (SSTAs) from 1949 to 1998. ...

Abstract: he ability of several atmosphere-only and coupled ocean?atmosphere general circulation models (AGCMs and CGCMs, respectively) is explored for the prediction of seasonal July?September (JAS) Sahel rainfall. The AGCMs driven ...
